Keith...
Just think of the number of pencils you will no longer have to 'sharpen'.. or perhaps even 'lose' out in the field... thus the number of trees 'saved' from being made into replacement pencils. You will no longer 'curse' the holes made in you pockets thanks to the small knives now no longer required for sharpening in the field . Think of the number of small 'sheets' of paper being lost.. or turned into 'pocket fluff' in the washing machine. You are now a 'free' man... as long as you remember to keep that Palm 'charged'.
